ROUG-H-ROUNDER FOR SHOES.

y No. 918,847.

Specification of Letters Patent.

Patented April 20, 1909.

To all whom it may concern:

Be it known that I, Donn H. HAnsnLL, a citizen of the United States, residing at Brockton, in the county of Plymouth and State of Massachusetts, have invented an Improvement in Rouglnltounders for Shoes, of which the following description, in connection with the ,accompanying drawings, is a specilication, like numerals on the drawings representing like parts. p

My invention relates to improvements in a Goodyear rounder for improving the efliciency of said class of machines for operating upon patent leather shoes. Y

I find that much ofthe imperfect workdone by roughrounding machines is due to their picking'up wax fromthe waxed thread used in sewing, and accordingly my invention resides in providing means for applying oil on the front side of the auxiliary guard or gage, which is providedfto move up and down in front of the main guard or edge Guide. b The further details of my invention and the various advantages thereof will be more apparent from the following description taken with reference to the accompanying drawing. l

In the drawing I have shown, in Figure 1, in front elevation, a machine containing my improvement Fig. 2 is an enlarged broken detail in side elevation.

For the purposes of this description it is unnecessary to explain all the details of the more or less complicated Goodyear rough rounder, which is a well-known machine.

The position of the shoe 1 is shown in full lines Fig. 2 and in dotted lines in Fig. 1, the outer angular lines 2 Fig. 1, indicating the edge of the surplus stock which is to be trimmed or rounded off.

The main guard or edge guide is shown at 3 in usual stationary position, through whose open lower end is arranged to pass the reciprocating rough rounder knife 4, which chops or cuts off the surplus leather in well-known manner. Immediately in front of this main guard plate or edge guide is an auxiliary or forepart guard or gage 5, shown in Fig. 1 in its uppermost position, and in Fig. 2 in its lowered operative position.V

At some suitable elevated position in the machine I provide an oil tank or reservoirf regulated by a valve '7 and connected by a flexible pipe 8 with a nipple 9 on the auxiliary or forepart guard or edge gage, the latter having a small oil vduct 10 opening just above the extreme lower edge of the gage 5 at the right hand or ingoing end of said age, as indicated at 11.

In use when the forepart of the shoe has been reached and it is desired to rough round the edges of the sole around the forepart, the operator lowers the auxiliary gage 5 from its position Fig.` 1 to its position Fig. 2, thereby pressing'the same down against the hollow or arch of the up er with the result that as the shoe is moved) along, a thin film of oil is deposited at the critical point where the ressure and strain are brought, the result being that the oil which oozes from the opening 11 is spread by the rapidly jogging, cutting movement of the knife 4 against the main guide 3, said oil being caused by said jogging movement and the movement of the shoe to spread downwardly over the leather and the face of the gage 5 and to a sufiicient extent over the edge of the guide 3 to prevent the damage to the shoe which has 'resulted heretofore. I have found that it is unnecessary, and in fact disadvantageous, to apply much oil and accordingly, by restricting the oil to the single small opening located at the particular point 11 above described, I find that exactly the right amount of oil will be distributed over that area, and only that area, and those surfaces which require it. Because of this special arrangement the machine Will not pick up wax which has been left on thel shoe by the waxed thread of the sewing machine. The laterally extended smooth face of the gage 5, with the single small lubricating vent at its ingoing side cooperates with the jogging motion and with the movement of the shoe to spread the oil in an exceedingly thin and practically imperceptible film at the precise region necessary to prevent this picking up of wax, without tending to oil the shoe appreciably or cause any disfigure'ment or injury even though the shoe be of a delicate high-grade class.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is,

1. In a Goodyear rough rounder, a main edge guide having a central opening for the passage of a knife, a cutting knife to pass transversely through said opening for rough rounding the sole, an auxiliary forepart gage, wedge shape in cross-section, adapted to rest the inseam when the sole is to be rough rounded against the shoe immediately in front of the lower edge of the main edge guide, a source of oil supply, a flexible tube from said oil supply to said forepart gage, and means for l controlling the oil supply from said tube, said forepart gage having a small oil duct opening at the ingoing end and adjacent the loWer edge of said foi'epart gage 2. ln a Goodyear rough rounder, a main edge guide adapted to rest against the Welt edge of the sole, a cutting knife 'cooperating With said vmain edge guide to rough round the sole, an auxiliary forepart gage ivoted to swing in front of said guide against t ie Vamp at about the forepart, said forepart gage having i a laterally extended smooth face for ahnmg and facilitating the movement of the shoe, an oil duct having a small opening at the ingoing end of said face adjacent the lower edge thereof, an oil supply and connections from the latter to said duct for maintaining oil at said opening to be spread over the surface of the gage and Vamp immediately vand at the said inseam as the shoe is slid forward away from said in'going end.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
